Publication number: 20240103869Abstract: Techniques for using CPUID for showing features that are deprecated are described. In some examples, CPUID is to include at least one field for an opcode, one or more fields to identify a source operand which is to store a LSL selector value, and one or more fields to identify a destination register operand, wherein the opcode is to indicate that execution circuitry is to, when the single instruction has been enabled by a setting of a bit in a control register, write a LSL value stored in the control register to the destination operand when the LSL selector value of the first source register operand matches a LSL selector value stored in the control register, and set a flag in a flags register.Type: ApplicationFiled: September 28, 2022Publication date: March 28, 2024Inventors: Andreas Kleen, Jason Brandt, Ittai Anati, David Sheffield, Toby Opferman, Ian Hanschen, Xiang Zou, Terry Parks
